Biography
Marcus Alphonse Murphy was a Black civil-rights activist and Communist Party defendant in the St. Louis Smith Act prosecution. He was indicted with four codefendants in 1952, convicted in 1954, and sentenced to five years in federal prison. The defendants remained on bond during their appeals. The Eighth Circuit reversed the convictions in 1958 after the Supreme Court narrowed the Smith Act, and the prosecution was abandoned. No service of the five-year sentence has been verified.
